Improved Vehicle Classification Using an Overhead Imaging LIDAR System with Axle Counting Capability. ITS-IDEA Project 65.

摘要

AUTOSENSE II is a product developed by Schwartz Electro-Optics, Inc. (SEO) under an ITS-IDEA contract with the National Academy of Sciences. This contract called for the development of a vehicle detector/classifier capable of accurate 3D profiling and classification of highway vehicles for speeds up to 100 mph. A scanning time-of-flight laser rangefinder concept was used which measured the normal distance to the highway from a fixed point above the road surface and then measured the distance to any vehicle that either passed under it or stopped beneath it. Autosense II Axle Count (Autosense II-A) is an advanced system for axle-based vehicle classification that will replace two or three existing systems.
